This is a spinal extension movement mostly without superincumbent weight,beginning at forward flexion and ending in marked hyperextension, calling theextensor muscles into activity from a stretched to a completely contracted condi-tion. It thus combines the range of motion in Exercise II with that of ExerciseIV. It is a heavier exercise than either. From the start of the exercise tillthe horizontal position is reached the spinal extensors and glutei are the muscleschiefly active, as the maintenance of balance does not require the contractionof other trunk muscles. The exercise may be made easier by placing the handson the hips. It is of use as a general strengthening exercise for the back musclesin any case where the patient is strong enough to take it. Exercises Lying on the Back.—The patient lies on a table or on the floor withthe head, trunk, and legs straight, and the feet secured either by a strap or bybeing held. The arms are folded on the chest. >. _ VI. Trunk Raising to Sitting Position.—(i) The patient rises slowly to thesitting position with the spine stiff and not allowed to flex. (2) The patient sinksto the priman, position with the spine still stiff, the head touching the tablebefore the back (Fig. 106). The exercise is made easier by placing the hands on the hips, and harder byplacing the hands behind the neck with the elbows squared back. The uprightposition is brought about by the contraction of the abdqminal muscles, which aidin maintaining the upright position, and require exercise in cases of prominentabdomen and of increase of the lumbar physiological curve accompanyingscoliosis and round shoulders. Miscellaneous Symmetrical Exercises . VII. Weight Carrying on the Head.—A bag filled loosely with sand, weighingfrom 3 to 15 pounds, is placed on the top of the patients head, and she walksslowly to and fro with the arms preferably clasped behind the neck and the e
